: Check engine light came on!

After work today I decided id have a little fun and do a couple of donuts in my work parking lot. (I have a N*) I turned the wheel left punched the gas and let the car spin a little, I then proceeded home. About a half mile later my CEL came on! I pulled over checked all the fluids, the MAF sensor, the airbox, and anything else that could have gotten loose and it all looked fine. Bolts are also tight on the intake manifold.
I just freakin bought this car and the dealer service for new hoses, fluids, and general upkeep of the car was about 3k miles ago. It has 75k miles. The car is running exactly the same, its not lagging or running hot.
Does anyone have an educated guess on what the issue could be before I take it somewhere to pull the codes? ECM? Emissions? ....?

I assume you defeated the traction control in order to burn your tires. Even if you left it off for the drive home, I can't guess how that would light the CES.

Autozone (& many competitors) will read the codes for free.

Do you use Top Tier gas? What octane?

T/c was off. And I use only 91 octane (that's the highest in the stations around me)

Your goose is cooked. All the dealer has to do is download the data from the ECM(freeze frame) and they will know exactly what you were up to.

..? Ok. I don't have a warranty so that doesn't mean much to me. I'm hoping I just triggered the o2 sensor or something simple. The manual says a steady CEL is only an emission issue apparently. So perhaps the donuts were completely coincidental.

My light frequently comes on when I use the remote start. It will go off after I tighten the gas cap and/or fill the gas tank. I don't notice any change in driving so I have not taken it in. If you do, let me know what the issue is.

The donuts are a preview of all the zeros on the end of the number on the repair bill.

Could be bad camshaft sensors.
I've had my check engine lights go on before due to this problem and had the dealership take care of them under warranty.

Everyone should own a scanner, be sure to get one that supports Can-Bus.

Pull your code, google it, read-up, you might be able to deal with this yourself :)

My CPS codes required only the cleaning/greasing of the 4 connectors....

This was one of the advantages of the pre 05 body style
You could read the codes from the instrument cluster display

wonder why they dropped that functionality in 05?

Probably created too many busybody car owners who used the incomplete information from that display to wrongly argue with their mechanics. Or more likely - lawsuits from owners who did their own repair based on the one or two simple codes and royally screwed up their car because they didn't have the full computer readout on the car's symptoms.

Gee, guess I'm feeling extra cynical today. Sorry, but I bet I'm right. I have my own little basic reader that works through my iPhone. It's enough to let me know what the main/top level error code is and provides the basic interpretation of the code, but like the basic light they all just mean get to a mechanic with the right tools to fully diagnose the situation.
